Rose plant--Meinimo variety

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and continuously forms attractive fully double very long lasting blossoms which exhibit a very soft and delicate Dawn Pink coloration. The blossoms exhibit a spicy fragrance. The plant exhibits a bushy growth habit, reddish-brown adult wood, forms vigorous and strong vegetation, and is well suited for service as attractive ornamentation in parks and gardens. Additionally, the plant is not particularly affected by cryptogamic diseases.

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the Meigurami variety (nonpatented in the United States).The male parent (i.e., the pollen parent) was the product of the crossof the Meinaregi variety (nonpatented in the United States) and theMeidragelac variety (nonpatented in the United States). The parentage ofthe new variety can be summarized as follows:

    Meigurami×(Meinaregi×Meidragelac).

The seeds resulting from the above pollination were sown and 234 smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

(a) forms in abundance on a continuous basis attractive very longlasting fully double blossoms which exhibit a soft and delicate DawnPink coloration,

(b) forms blossoms which exhibit a spicy fragrance,

(c) forms reddish-brown adult wood,

(d) exhibits strong and vigorous vegetation,

(e) exhibits a bushy growth habit,

(f) is particularly suited for growing in parks and gardens, and

(g) is not particularly affected by cryptogamic diseases.

The new variety well meets the needs of the horticultural industry andis particularly well suited for use as attractive ornamentation in thelandscape.

The new variety has been found to undergo asexual propagation by anumber of routes, including budding, grafting, cuttage, etc. Asexualpropagation by the above-mentioned methods as performed in France hasshown that the characteristics of the new variety are strictlytransmissible from one generation to another.

The new variety has been named the Meinimo variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed during Junewhile budded on Rosa froebelli understock and growing outdoors atLeCannet-des-Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of two year old plants made during June while budded onRosa froebelli understock and growing in outdoors atLeCannet-des-Maures, Var, France. The coloration in common termsprecedes reference to the chart.
